Vance, the bottom two pictures look like an entirely different tree than the top two pictures!
Was the trunk buried deep in the training pot on the last two pictures? That's quite the transformation!
Also, it looks like you successfully dealt with the knob that appears to be an inch above the soil in the bottom pictures. Those knobs are very common on Mugos, at least the ones I see. And a major drawback to using Mugo, at least for me. But, your latest pictures don't have a knob! I'd like to know how you deal with the knobs. Perhaps that would be a good subject for a video! I haven't messed with a Mugo in years. When I did, and tried to prune off part of the knob on my tree, the resulting callous was as bad or worse as the original knob! Your insight on this problem I'm sure would be appreciated by many of us.
